Mary J. Blige stopped by the Wall Street Journal’s WSJ Cafe recently to help celebrate the holiday season by singing “This Christmas” from her new album “A Mary Christmas.” Now that Christmas Day has arrived, we’re reposting the video for your holiday enjoyment. “This Christmas,” co-written Nadine McKinnor and Donny Pitts (Donny Hathaway’s stage name) was first released by Hathaway in 1968, and has also been covered by Diana Ross, Chris Brown, Pentatonix, and many others. Blige knocked out her rendition of the song at the WSJ Cafe in just one masterful take.
